New energy vehicles such as electric vehicles are the new transport with good prospects for the development. However, waiting hours to recharge the batteries limit the large-scale applications of electric vehicles. The high mobility rate electrolytes and stable solid electrolyte interfaces are the basic materials for the rapid charging lithium batteries. This project focus on the diffusion processes of lithium ion in the liquid electrolytes and solid electrolyte interfaces by the first principles molecular dynamics simulations and density funct...
